Y ing Apparatus, of which thefollow-ing is a specification. Y

lThis invention relates to a Ventilating apparatus. Its object is the production of apparatus by means of which the` atmosphere of tunnels, subways and the like is prevented from contamination by the exhaust from motor vehicles. A Vsecond object ofthe invention is to ventilate tunnels and subways and to prevent the accumulation therein of noxious gases. The third objectvof the invention isto draw the exhaust from a motor driven vehicle as' it moves through a tunnel or subway and discharge it outside of the tunnel or subway.

'In the accompanying drawings Fig. 1 rep-v resents across-section as-on the broken line I, I, o-f Fig. 2, of an exemplif'lcation of the venti-lating apparatus; Fig. 2 shows a partial 1 side view and section of Fig. 1 on the line 2.v

2;*Fig.- 3 indicates 'the end view of ia detail; Fig.v 4 is a partial top' plan view of Fig. 1 and Fig. 5 is an enlarged view of aV portion ofFig.1.' -v

Thefloor ofla tunnel is indicated at 20 with longitudinal depressions 21- for Ithe wheels of a moto-r vehicle, not shown. An exhaust duct is indicated in its entirety.. by the letter A. and comprises the :inner side walls 22, 23 wit-hl the upper `longitudinal flanges 24` that constitute tracks.' The bottom wall 25 of the duct extends beyond theV said sidev walls and connects with-the outer side walls' 26, which latter have formedr therewith the upper lflanges 27. Wheel guards 28 with the depending flanges 29 are fastenedr to the flanges 27. lBranch outlet pipes 30 extend from the duct A. -A shelf 31 Awith 'the flange 32 extends -fro'm'each` wall' 26. The walls 26are made' in'f'sections with.

the abutting flanges 38fthatare 1 bolted to each other. 'An exhaust pipe :40 islocated, in thisinstance, under thevduct-A and has extending therefrom branch pipes'41, that are detachably, connected: tov the branch y'pipes 30.

A- pluralityl of. valve chambers B 'are formed in the duct A, andNcomprise the cross walls 42 with they upper cross flanges 43, the lower-'cross flanges 44? and thebottom walls 45.3.Lower valve-portse vare formed with the kbottom flanges 44 and the bottom walls 45, and upper valve ports 48 are formed. with the cross flanges 43 and the flanges 24.

A valve 52 is located in each of the valve chambers B. A hinge member 53 is formed with each valve 52, and a pair of hinge members 54 are formed with one of the flanges 44. A hinge pin 55 extends through said hinge members. c A stuffing box C is formed in the wall 23 for each of the valvechambers B.

Aspindle 56 extends through each stufling flanges 66a.. The flanges 66 bear on the tracks 24 and have formed therein the port 67. YEnd walls' for the trolley are indicated at 68, which latter join with the roof 69. An inlet pipe 70 lwith the'flange 71 is formed with the roof 69. The flange v71 has extending therefrom the 'annular flange 72. The walls 65 extend beyond the end wallsV 68 and have formed therein the elongatedopenings 75. ySpringse'ats 76 extend from the roof 69 and are connected by the rib 77 which joins with said roof. Detachable springr seats 78 `are coaxial with the spring seats 7 6 'and `are fastened to the' walls 65 of the trolley. Axle bearings 80fhave extending. therefrom the guide plugs 81 which are guided in the spring seats 76 and 78.

Springs 82 are located in the said spring seats and bear against theguide plugs 81. Axles 88 are journaled inthe bearings 8O and have fastened Vto their ends the wheels 90,'which`wil1 rollon the shelves 31, and are coveredv by the wheel guards 28. A cam E is fastened 'to yone side of the trolley D, and has `formed therewith the; inclined yupperwalls92 'and-93, which are in line with therollers 63j An elbow isshown with' the horizontall lower flange95; and thevertical flange 96. The flange 95'bears on thefiange 71. A plate rinej98iis fastened to'the flange 72 and engages the flange 95, to enable the latter to swing.

dcorrugated intake pipeis 4indicated in its entirety bythe letter H and at one end thereo).C fastened ,the flange 100, which. is

bolted to the ange 96 and adjacent to its other end is fastened a ring 101 with a plurality of pairs of eyelets 102.

A clamping deviceis designated in its en= tirety by the letter I. The clamping device comprises a plurality of arms 106i whichat one end are hinged to the pairs of eyelets 102. The arms 106 have extending fIllIy their other ends the members 107, which latter at theirtop ends havev formed therewith the forks 108 andL at their lower ends are formed the jaws'109. Gri'ppers'll@ are hingedto the jaws 109. A chain 112 has one end thereof fastened to one of the members 107 and then extends through the forks 108.` A hook'113 is fastened to the other end of thechain 112.

A U shaped support 115 has extending therefrom the rods 116 which are slidably supported lin theY flanges 96 and 100. The support 115 is provided for the pine H.

vChains 120 have one end each fastened to the walls65 ofthe trolley D and their other ends are fastened' to the vehicle which runs through the tunnel. The exhaust pipe? of the vehicle ifs indicated at, K.

The apparatus is indicated as located below the floor level 20 of the tunnel and in the concrete foundation 125" thereof. At a predetermined distance a shaft 126 is formed in the concrete which connects with a longitudinalv chamber 127 below the wall: 25". A detachable cover 130 is providedI for the shaft 125 and thereby'pmeans are pro'- vided to inspect the pipe 10 and' make any necessary repairs thereto.

Various modifications may be made' in the invention andi the present exemplifiea-Iv tion is to be taken afs illustrative and not limitative thereof. Y

To operate. the apparatus the clamping device I is fastened to the exhaust pipe K by locating the grippers 110" on the' pipe and tightening the chain 112 so that the" said grippers tightly' cla-mp thek said pipe'. The chains 120 are fastened to' the vehicle which is to' run throughf the' tunnel'. When the vehicleT moves the trolley DI willI move` therewith, the' wheels 90 rolling on the shelves 31. An exhausting apparatus, not shown, isr connected to the` pipe 10", When the trolley DE' moves: therollersy 63 will' en`j gage the cam E and While`v it moves-' over each valve chamber Bf the valve 52'wi'll be`v opened and closed. Before the trolley uncovers the port 48 of one valvechamberf its port 67 isi inf connection with the port 458`of`the next adjacent valve'chamber. The exhaust Afrom the vehicle enters 'the' valve chamber B and is drawn into exhaust pipe 40? and then discharged from the latter. The gases left in each chamberB after its valve 52`closesf is drawn: into: the' next adjacent valve? chamber B as the trolley `D- rnovesziA If desired any' of the'valves 52 may be opened tov ventilate the tunnel without employing the trolley D. While the trolley moves through the tunnel the suction in the valve chambers B tends to draw the trolley D to thev tracks 24, so that the leakage between said track and the flanges 66 is rednced to a Having described my invention what I desire to secure by Letters Patentand claim 1s:
